The 32-bit port processor communicate on both the high-speed bus and standard packet
bus. Should there be a failure on the high-speed bus, the 32-bit port processor
automatically revert to the standard bus and notify IENView. If a port processor is removed
or powered off, the other port processors detect this state, and an alarm is transmitted to
IENView.
Standard Bus
Similar to the high-speed bus, the standard bus is used to transmit data frames between
port processors. The standard bus supports all port processors. The 32-bit port processors
use the standard bus for communication with the first generation port processors, and as a
backup to the high-speed bus. The first generation port processors use the standard bus for
all data communications. Figure 2-17 illustrates the standard bus.

If a port processor is removed or powered off, the other port processors detect this state,
and an alarm is transmitted to IENView.
